For cordless telephone
Question Suggestions
1. The telephone does not work at all.
• Make sure the Cat-5 network cable
is plugged into the LAN port of the
telephone base and the network wall
jack with Power over Ethernet (PoE).
• Make sure the battery is installed and
charged correctly. For optimum daily
performance, return the cordless handset
to the telephone base or charging stand
after use.
• Unplug the Cat-5 network cable from the
network wall jack. Wait for approximately
15 seconds, then plug it back in.
• Charge the battery in the cordless handset
for up to 16 hours.
• If the battery is completely depleted,
charge the battery for at least 30 minutes
before use.
• Remove the battery and then install it
again. If that still does not work, it may
be necessary to purchase a new battery.
• Disconnect the telephone base from the
network wall jack and connect a different
working SIP telephone. If the other SIP
telephone does not work, the problem is
probably in the wiring or network server.
Check your SIP server settings. Refer to
the SIP Phone Configuration Guide for
details.
• Make sure the energy-saving charging
mode is not activated. If this mode is
activated, all telephone functions will be
disabled, except battery charging.
